1. **Problem statement:** We have a piecewise function
$$h(x) = \begin{cases} -2x + 4 & \text{if } x \leq 1 \\ x^2 + 1 & \text{if } x > 1 \end{cases}$$
We need to find the value of $h(3)$.
2. **Identify which piece to use:** Since $3 > 1$, we use the second piece of the function:
$$h(x) = x^2 + 1$$
3. **Calculate $h(3)$:** Substitute $x=3$ into the second piece:
$$h(3) = 3^2 + 1 = 9 + 1 = 10$$
4. **Answer:** The value of $h(3)$ is 10.
Therefore, the correct choice is (A) 10.
